An ion is an atom which has more or less electrons than protons. If it has more electrons it's a negative ion, and if it has less electrons it's a positive ion. An atom loses or gets electrons in reactions with other elements.

Removal of an electron from an atom leaves a positively charged ion.


What do you call an atom that gains or loses electrons?

An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.


When electron transfer results in an ion larger than the original atom?

When electron transfer results in an ion larger than the original atom, it is likely that an anion has formed. This occurs when an atom gains electrons and becomes negatively charged. The additional electrons increase the electron cloud size, making the ion larger than the original atom.


When an atom gains or loses electons the charged particles that results is called?

an ion


When an electron is removed from an atom it i considered what?

When an electron is removed from an atom, it is considered to be ionized. This results in the formation of a positively charged ion known as a cation, while the atom itself becomes positively charged.


What is the term for a single atom bearing a negative or a positive chargeas a result of gaining or losing valence electrons?

An ion is a single atom that carries a positive or negative charge due to gaining or losing valence electrons. The atom becomes an ion when it has an unequal number of protons and electrons.


How many electrons does the calcium ion lose from an atom?

A calcium ion (Ca2+) loses two electrons from an atom to achieve a stable octet electron configuration. This results in a +2 charge on the calcium ion.


Does a sodium atom lose or gain electrons when it becomes an ion?

Sodium loses its one valence electron to become Na+


An atom that has lost or gained electrons is an?

When a sodium atom becomes an ion it does what?

A sodium atom would lose a electron so it would become a Na+ ion


What process would turn this fluorine atom into an ion?

The fluorine atom can become an ion by gaining one electron to achieve a stable electron configuration of 8 electrons in its outer shell. This results in the formation of a negatively charged ion known as fluoride ion (F^-).


Which type of chemical bonding results from the transfer of electrons?

Ionic bonding results from the transfer of electrons between a metal and a nonmetal atom. The metal atom loses electrons to form a positive ion, while the nonmetal atom gains electrons to form a negative ion. The opposite charges attract, creating the ionic bond.
